T 0 all who/n it may concern.' y Y Be it known that l, ALEXANDERMITCHELL, a citizen of the United States, residing at Pueblo, in thecounty of Pueblo and State of Colorado, have invented certain new anduseful Improvementsin Flows, of which the following isa specification.

rl"his invention relates to agricultural implements and' has for itsobject the provision of simple and inexpensive means whereby a plow,harrow, cultivator or other implement may be operated .withoutemployi-ng draft animals. l p

In carrying out the invention l make use oit' velocipede structure,preferably in the form of a tricycle, driven by the feet orp the rideror by motor or otherwise, and whose details of construction areunimportant excepting that its frame carries a draw bar projectingrigidly to the rear and obliquely, downward over and beyond the drivingaXle, and this bar in turn carries an adjustably mounted earthengagingimplement or blade such as a plow. In other words, the gist ofthe invention is making use of the so called velocipede structure bothto support the draw bar at a fixed angle to the surface of the earth andto drag the blade along the desired line of work, whereby the ridersimultaneously directs the plow and guides the propelling element, andin some cases drives the latter himself, and meanwhile his weight holdsthe blade to its work and he may vary its angle as desired.

The invention is illustrated in the accompanying "drawings and will behereinafter fully described, the novel features being subse uentlyparticularly set torth'in the claims.

n the drawings Fioure 1 is an elevation of a plow embodyin y tieinvention.

ig. 2 is a plan view of the same. v

ln carrying out my invention, I employ a velocipede or tricyclestructure having a frame comprising a perch 1 at the front end of whichis a steering, head 2 having a fork 3 mounted therein, said fork havinga steering wheel 4 mounted in its lower end and being provided with ahandle bar 5 at its upper end. The perch 1 has its rear en d fitted in acoupling-6 which also receives and secures the seat post 7 on the upperend of which is a saddle 8. Hangers 9 rdepend from the steering head andthe said coupling 6 and support the propelling mechanism.

Bracesv 1() diverge downwardly from the coupling (l and carry the'axle11 in their lower ends and driving-wheels 12 12 Aare mounted on the endsof the axle while a sprocket wheel 15 is secured thereon near the centerthere-of. Either or both the driving wheels may be rast on the axle.That numbered 12 in the drawingswill travel on the land side and thatnumbered 12 will travel on the plowed ground, and their tires and treadsl. should prefer that the landside driver be fast on the axle it' theplow 23 (described hereinafter) is employed, because its share ywillproduce side lash-of the beam tending to swing its rear endtoward thatwheel. A sprocket chain 1e is trained around the sprocket and' asprocket pinion 15 secured upon the driving shaft 16 journaled in thelower portion oi' the frame presented by theV hangers 9. The drivinglshaft carries avly wheel 18 and is shown as equippedwith cranks 19at'its ends, said cranks having pedals 20 which may be easily `engagedby an operator from Vthe saddle S. i motor may be mounted upon the frameto operate the driving shaft, if de. sired.

T he link is preferably provided with, a plurality lofopenings through. any'oic which the connecting pivotpin may be insertedinto the standard so that theangle of penetration oi the plow maybevaried as required.

The operation is thought vto be obvious.

yA rider upon the saddlel applies rotating force through his feet to thepedals 20 or controls the motor so that the crank shaft" and the pinionthereon will be rotated. The motionpor" the driving shaft is transmittedto the axle 11 and the wheel 12 so that thev machine will travel overthe' field and the Adraw bar 21 will drag the plow'V throughSpecificationv of Letters Patent. patinte@ Slept. 7, llgtl. vApplicationfiled.l March 5,

The machine is very siinole and compact and may be easily operated.
